Building eLua in Linux

Building eLua in Linux

Building eLua in Linux is fairly easy. This tutorial assumes that Ubuntu is used for building, however any distro should be fine, you just need to
convert the "apt-get" calls to your distro's package manager equivalent. You need a few packages installed to build eLua:

a toolchain: check the toolchains page for
toolchain instructions. Please note that even if you already have a
compiled toolchain, the differences in the Newlib configure flags
(mainly the --disable-newlib-supplied-syscalls flags) might prevent eLua
for building properly on your machine.

Python : it should be already installed. If it's not, use
apt-get to install it:

$ sudo apt-get install python

scons - eLua uses scons instead of make
and makefiles, because we find scons much more "natural" and easier to
use than make. To install it:

$ sudo apt-get install scons

your toolchain's "bin" directory (this is generally
something like /usr/local/cross-arm/bin, where /usr/local/cross-arm is
the directory in which you installed your toolchain) must be in $PATH.

if you're building for the i386 platform, you'll also need
"nasm":

$ sudo apt-get install nasm

gcc: if you want to use the ROMFS precompile feature (see here for details) you need to build an image of the eLua cross compiler, and you need an i386
toolchain for this. It should be already installed, but if you want to be on the safe side do this:

sudo apt-get install build-essential

Then build the eLua cross compiler by executing this command:

scons -f cross-lua.py

After you setup your build environment as described above, follow this tutorial to build your eLua image.
